面对全球控制温室效应的呼声,低碳经济已成为世界发展的趋势。未来10年,我国经济将继续保持较快的发展速度,老百姓的生活水平和生活质量也将进一步提高。与之相对应的是,中国碳排放总量和对能源的消耗也将会继续增加。在此情况下,到2020年实现碳排放下降40%~45%的目标难度不小。 相似文献

This work utilizes the Regional Energy Deployment System (ReEDS) model to analyze the impacts of four nuclear retirement scenarios of the U.S. electricity sector, from nuclear plant lifetimes of 50 to 80 years. The analysis finds that longer nuclear lifetimes decrease the amount of renewable and natural gas capacity. Longer nuclear lifetimes also resulted in lower cumulative and annual carbon emissions, lower transmission builds, and higher energy curtailment and water usage. 相似文献

The U.S.-Canadian power system has evolved into a highly integrated grid. Cross-border transmission and coordination of system operations create an interconnected power system with combined imports and exports of electricity of greater than 77?TWh per year. Currently, more than 5 GW of new international transmission lines are in various stages of permitting and development. These transmission lines may enable even greater integration and coordination of the U.S. and Canadian systems, which can in turn increase the reliability and flexibility of North America’s electricity grid and help address challenges associated with integrating high levels of variable renewables. Using a version of the National Renewable Energy Laboratory’s Regional Energy Deployment System (ReEDS) model that incorporates Canada, this analysis quantifies the differences in the evolution of the power system under scenarios in which cross-border transmission capacity is restricted to today’s levels, and scenarios in which new transmission is less restricted. These impacts are analyzed under a “business-as-usual” reference scenario and a scenario in which deep cuts in power sector carbon dioxide emissions levels are achieved. A set of key impact metrics is analyzed, including 1) the composition of generating capacity by technology, 2) system costs, 3) wholesale electricity prices, 4) international electricity exports and imports, 5) transmission capacity, and 6) carbon dioxide emission levels. When new cross-border transmission is not allowed, the United States needs additional capacity (primarily natural gas and renewable energy) to meet domestic needs, while total Canadian capacity is lower because less capacity is needed to export to the United States. This effect is amplified under the carbon cap scenario. Impacts vary on a regional basis, largely due to the different relative sizes of the generation portfolio between countries and regions and the relative impact from cross-border electricity trade. The total impact from restricting cross-border trade on carbon emissions and average wholesale electricity prices is limited, due to the relative size of the domestic power systems and the cross-border trade volume. Cross-border transmission capacity is projected to more than double under the unrestricted transmission capacity scenarios, which exceeds the rate of projected domestic transmission capacity additions in each country. 相似文献

Carbon capture utilization and storage is an important technology option to rapidly and profoundly decarbonize the power sector, but will not deploy without substantial incentives or regulation. Assessment of U.S. policy options reveals that current incentives only partially close the finance gap and are most sensitive to fuel type and ownership structure. Recent proposed legislation would in some designs attract private investment for many projects, leading to widespread deployment of CCUS in the power sector. Additional constraints and concerns (including technology options and presence of CO2 infrastructure) could play an important secondary role. This study discusses the specific US incentive policies that can provide investors and lenders with net cash flows that are adequate to attract private capital to CCUS power projects in the US. 相似文献

With the impending transition in energy policy, the inevitability of political transitions should be accounted for in order to avoid an unsustainable shift in policy that is short-lived and introduces uncertainty for the U.S. power sector. A policy correction rather than an outright reversal can offer a middle ground for energy-environmental centrists to sustain pragmatic energy policy through political transitions, and engagement in international climate talks independent of the administration’s position on climate change. 相似文献

燃煤发电是我国主要的电力来源,它的成本比较低,但同时带来了污染严重的问题.目前我国已开始在大容量燃煤发电机组中普及脱硫装置,而国外目前的主要研究方向是如何控制燃煤电厂的温室效应气体的排放.为了解决燃煤发电的污染问题,2003年,美国能源部宣布了一项计划:将在10年内投资10亿美元设计、建造和运营世界上第一个零污染燃煤示范电厂.该电厂被命名为未来电厂(FutureGen),将安装总容量为275 MW的燃煤机组,这座世界上最清洁的燃煤电厂将运用先进的无污染能源技术建造一个原型电厂,作为一个大规模的工程实验室,用于试验新的清洁能源技术、二氧化碳捕捉技术和煤氢转换技术.预计未来电厂将在2020年投入商业运营. 相似文献

For more than 20 years, the large-scale application of flue gas desulfurization technology has been a dominant cause of SO2 emission reductions. From 1994–2004, electricity generation from coal increased, but the shift to low-sulfur coal eclipsed this. From 2004–2014, electricity generation from coal decreased, but a shift to higher-sulfur subbituminous and lignite coal overshadowed this. The shift in coal quality has also created a CO2 emissions penalty, representing 2% of the sector’s total emissions in 2014. 相似文献

In the 20th century, the U.S. established itself as the global leader in nuclear science, engineering and technology, in large part because of policy principles established in the 1940s and 1950s. However, with 20% of its current nuclear fleet at risk of premature closure, limited nuclear construction projects on the horizon and increased competition from state-owned nuclear programs in China and Russia, America’s 20th century legacy of leadership may not be sustained in the 21st century. 相似文献

A review of the frequency regulation market practices of the ISO New England, PJM Interconnection, and Midcontinent ISO is presented here. Particular attention is given to market structure, resource eligibility, selection, market clearing and settlements. An overview of frequency regulating reserves and the capacity and performance components is provided. We find that the observed spread in historic market clearing prices can be explained by how each operator incorporates lost opportunity cost into their clearing formulation. 相似文献
